Fog, cooler temperatures roll into Southern California

Southern California was headed for a brief cool-down Wednesday as low clouds and dense fog rolled into several locations.

A dense fog advisory was issued for valley areas in Los Angeles and Ventura counties until 10 a.m.

“There is a weak trough of low pressure moving across the West Coast that is going to create a bit of a cool-down today and tomorrow,” said David Sweet, a meteorologist with the National Weather Service in Oxnard. “Temperatures will not be quite as warm as they have been inland.”

Sweet warned of reduced visibility to a quarter of a mile or less, making driving conditions hazardous.

He advised motorists to “drive slowly, use low-beam headlights and leave plenty of distance from the car in front.”
